I would like to create memory file systems for several areas. Some custom directories, but specifically /root/.cpan and /var/www/htdocs

Also any areas involved in building packages. I'm hoping to create startup scripts that will populate these areas with cached copies elsewhere. With rsync I think I can sync the web folder every 5 minutes and be just fine. The CPAN environment much less often, and only during upgrades I think.

I'm spending about an hour or so creating servers, and so much of it is initialization in CPAN and subsequent installing of Perl modules. On top of that I have an awful lot of work being done in the web folder, and having it in memory will be a real boost to performance.

That's my use case. I'm hoping you can advise me on your setup since it sounds like what I'm looking for.
